Which of the following is cytidine? cytosine + guanine ribose + cytosine + phosphate group ribose + cytosine cytosine + deoxyribose
Which type of covalent bond is present in a “charged” transfer RNA molecule (with an amino acid attached), but absent in an “uncharged” transfer RNA molecule (without an amino acid attached)? the aminoacyl bond the phosphodiester bond the peptide bond the glycosidic bond the ether bond
Which of the following statements is correct Adenine is a purine and uridine is a pyrimidine Thymidine is a pyrimidine Adenine and guanine are both purines. Adenine and cytosine are pyrimidines
All of the following are true about RNA, except: RNA is not a double-helix RNA has thymine as a base. RNA does not contain deoxyribose RNA has Uracil as a base In RNA, Cytosine and Guanine are base pairs.
Which of the following is an RNA nucleoside? cytosine and ribose B a phosphate group, uridine and ribose (C) thymine and ribose adenine anda phosphate group
RNA molecules are more easily broken down than DNA at a high pH. This can be attributed to the fact that: RNA has a higher melting temperature than DNA. RNA contains uracil that helps break down the RNA, whereas DNA contains thymine. RNA is single stranded but DNA is double stranded. RNA is a smaller chain than DNA, which makes RNA easier to break apart than DNA. RNA contains an oxygen at the 2' carbon of its ribose sugar whereas DNA does not.
The following statements best describe the RNA structure EXCEPT they are double stranded because many bases are complementary to each other they are closely associated with protein synthesis they can either form secondary or tertiary structures there are three predominant forms

Which one of the following statements about nucleic acids is correct? Multiple Choice NTPs can be incorporated into either DNA or RNA molecules, but dNTPs can only be incorporated into DNA molecules A nitrogenous base, 5-carbon sugar, and two phosphate groups would most accurately be referred to as a nucleotide diphosphate. During nucleic acid synthesis, the phosphate group at the 3' carbon of the incoming monomer is covalently linked to the hydroxyl group at the 5' carbon of the existing macromolecule. RNA and DNA have all the same pyrimidine bases in them, but differ in the selection of purine bases. A nucleic acid found in a cell with the sequence GCCTTATCGCG would most likely be found paired with another molecule in double-stranded form.
